Claim of US Patent No. 9,964,633

1. An infrared countermeasures system, comprising:a wide field of view sensor configured to receive infrared light from any direction;
a narrow field of view sensor configured to receive and emit infrared light along a repositionable direction,
the narrow field of view sensor including a pointing actuator configured to controllably reposition the narrow field of view sensor along the repositionable direction; and
a controller configured to receive and process data outputs from the wide field of view sensor and the narrow field of view sensor, provide a data input for the narrow field of view sensor, and provide a data input for the pointing actuator,
the controller to configure the wide field of view sensor and the narrow field of view sensor to:
emit first infrared light from the narrow field of view sensor toward a remote infrared countermeasures system, the first infrared light including data representing a Request To Send and a location of the narrow field of view sensor;
receive second infrared light with the wide field of view sensor from a remote narrow field of view sensor, the remote narrow field of view sensor being associated with the remote infrared countermeasures system, the second infrared light including data representing a Clear To Send and a location of the remote narrow field of view sensor; and
point the narrow field of view sensor toward the remote narrow field of view sensor in response to the location represented by the data in the second infrared light.
